Abstract
The present invention describes a collimating system comprising a plurality of collimating apparatuses forming an array. Each collimating apparatus comprises a light source 12, and a collimating optic 18a configured to collimate light received from the light source 12. The collimating system further comprises a homogenising optical arrangement 50 spaced apart from the array and configured to extend substantially perpendicular to collimated light exiting each collimating apparatus. The homogenising optical arrangement 50 is configured to receive light from each collimating apparatus, the received light having a non-uniform relative radiance profile. The homogenising optical arrangement 50 is configured such that light received from adjacent collimating apparatuses superimposes on exiting the homogenising optical arrangement 50, and forms a flattened relative radiance profile 48b.
